Using a scale-bridging technique to determine the effect of elastic properties on stress distribution around the femoral stem of an artificial hip joint with a simplified geometry
Metals and Materials International - Tập 20 - Trang 593-600 - 2016
A scale-bridging technique was used to investigate the effect of the elastic properties of β-Ti alloys on the stress distribution around the femoral stem of an artificial hip joint with a simplified geometry when under an external loading. The anisotropic elastic constants of single-crystalline β-Ti alloys (TN1: Ti-18.75 at% Nb, TN2: Ti-37.5 at% Nb, and TN3: Ti-43.75 at% Nb) were calculated using ...... hiện toàn bộ
An Experimental Investigation on the Deformation Behaviour of Recycled Aluminium Alloy AA6061 Undergoing Finite Strain Deformation
Metals and Materials International - - 2020
Finite strain deformation behaviour of recycled aluminium alloy AA6061 is investigated in this paper via uniaxial tensile test and Taylor cylinder impact test implementations. The uniaxial tensile tests are performed at different elevated temperature from 100 to 300 °C, at the strain rate of 10−4 s−1 and 10−3 s−1 and the Taylor cylinder impact tests are conducted at different impact velocity rangi...... hiện toàn bộ
Expansion of a low conductive metal tube by an electromagnetic forming process: Finite element modeling
Metals and Materials International - Tập 14 - Trang 91-97 - 2008
The expansion of a metal tube by means of an electromagnetic forming (EMF) process is attractive because EMF has a high forming rate and can reduce residual stress. The forming forces in EMF are Lorentz forces. They are derived from a repulsive interaction between a transient electric current induced in a coil with the aid of a capacitor bank and an eddy current induced in a metal tube by means of...... hiện toàn bộ

Microstructure and Texture Evolution of Rolled Plate for Cu–15Cr In-Situ Composite
Metals and Materials International - - 2020
The microstructure and texture of different rolling processes in situ Cu–15Cr sheets are studied. The results show that the second phase Cr in the material gradually become broken, flattened, merged and homogenized from dendritic state to oriented thin lath. Meanwhile, the texture in distributed copper matrix grains finally forms Brass {110}<112>, Goss {001}<110> and Copper {112}<111> textures along with Cr phas...... hiện toàn bộ

Các tiếp xúc ohmic Pd/Ge (hoặc Si)/Pd/Ti/Au cho InGaAs loại n trong HBT AlGaAs/GaAs Dịch bởi AI
Metals and Materials International - - 2004
Các tiếp xúc ohmic Pd/Ge/Pd/Ti/Au và Pd/Si/Pd/Ti/Au cho InGaAs loại n đã được nghiên cứu cho các ứng dụng trong tiếp xúc ohmic của bộ phát HBT AlGaAs/GaAs. Trong tiếp xúc ohmic Pd/Ge/Pd/Ti/Au, một điện trở tiếp xúc đặc trưng tối thiểu là 1.1×10−6 Ωcm2 đã đạt được bằng cách thiêu kết ở 425°C trong 10 giây, nhưng hiệu suất ohmic hơi giảm khi nhiệt độ thiêu kết tăng do phản ứng giữa các vật liệu tiếp...... hiện toàn bộ
Preparation and characterization of Mg alloy rods with gradient microstructure by torsion deformation
Metals and Materials International - Tập 22 - Trang 887-896 - 2016
Extruded AZ31 Mg alloy rods were subject to free-end torsion deformation at room temperature. The microstructure features of the torsion deformed samples were characterized using electron backscatter diffraction technique. Mg rods with gradient microstructure can be fabricated by torsion deformation. Inhomogeneous distribution of microstructure along the radial direction of the twisted rods is att...... hiện toàn bộ
Microstructure evolution and modeling of 2024 aluminum alloy sheets during hot deformation under different stress states
Metals and Materials International - Tập 24 - Trang 112-120 - 2018
In this work, specimens of the 2024 aluminum alloy sheet were compressed and stretched along the original rolling direction at elevated temperatures. The microstructure evolution was investigated by characterizing the metallographic structures via electron backscattered diffraction technology before and after deformation. It was found that while recrystallization occurred in the compressed specime...... hiện toàn bộ
